Record heat prompts fishing closures across US West

Record summer heat has driven river temperatures to lethal levels for trout, prompting wildlife officials to ban fishing during certain hours across the U.S. West. After a dry winter and amid widespread drought, lower water levels accelerate warming. Restrictions now cover 1,200 miles of rivers in Montana and 635.5 miles in Colorado, with Yellowstone National Park expanding afternoon closures. More record temperatures are forecast as a heat wave expands.
